Abstract
The present study considers the damage mechanisms and the rainfall in fi ltration process responsible for landslide phenomena which originate from accumulation slopes. Accordingly, a physical test model is developed for different slopes and different rainfall conditions. Moreover, a three-dimensional laser scanner and a camera are used to monitor the slope erosion and the landslide dynamic evolution. Using this approach, the time variation curves of volumetric water content, pore water pressure, soil pressure, slope deformation, and damage are determined. The results show that under similar conditions, similar trends of the pore water pressure are achieved for different slopes and rainfall intensities.
期刊介绍:
The scope of the Journal is covered by these topics (which could be updated): interplay between fluid motion and materials preparation processes (by means of: experimental investigation; computer modeling & simulation; novel numerical techniques and multiprocessor computations); multi-phase and multi-component systems; pattern formation; multi-scale modeling; interface-tracking methods (e.g., VOF, level-set) and moving boundaries; fluid-structure interactions; solidification; semiconductor crystals; metallurgy; dynamics of dispersed particles, bubbles and droplets (sedimentation, Marangoni migration, coalescence mechanisms, interaction with advancing fronts, etc.); dynamics and static behavior of fluid surfaces and interfaces.
